Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair Decorations, all still belong within the invention patent covering scope.
It refering to fig. 1-10, is a kind of flexible fixture based on CNC processing of the present invention, including for being fixed on lathe Bottom plate 11 on workbench 1, one end of the bottom plate are fixed with connecting plate 22, and backing plate 12 made of bakelite material is fixed on the connection When processing through-hole on plate, on workpiece can backing plate upper plane there are cutter trade (through-hole can be processed on workpiece), pad Plate can re-work plane reparation after using to a certain extent.Two adjacent lateral surfaces of the connecting plate are fixed respectively Having height is more than the locating piece 13 of plane on the backing plate;Other two opposite lateral surface of the connecting plate is respectively equipped with one and pushes away Plate 14, each push plate are individually fixed in a push plate driving mechanism, which is able to drive the push plate along the push plate Vertical line direction back and forth movement;The upper surface of each push plate 14 is respectively fixed with gripping block 15, the inner end activity of the gripping block It is placed on the upper side of the backing plate.In use, bottom plate 11 is fixed on platen 1, workpiece 6 is placed on backing plate 12, Then two push plate driving mechanisms, which are respectively started, drives corresponding push plate 14 to travel forward, and workpiece 6 is made to be fitted in two locating pieces 13 Between gripping block 15, headroom above workpiece is realized, to realize clamping positioning, can carry out through-hole, stepped hole and groove milling With the milling working processes such as shape.
Wherein, the push plate driving mechanism includes linear guide 16, the sliding block being slidably disposed in the linear guide 17, and The cylinder 18 of the vertical push plate setting, the lower end of the push plate are fixed on the sliding block, and the cylinder block 181 of the cylinder is solid Due on the bottom plate, the piston rod 182 of the cylinder passes through floating junction 19 and the push plate floating connection.The push plate Lateral surface is equipped with fixing seat 20, and the floating junction 19 is connected in the fixing seat.The piston rod of cylinder 18 is connect by floating First 19 and fixing seat 20 connect with push plate 14, to drive push plate campaign, gripping block 15 is driven to clamp workpiece.And push plate passes through sliding block 17 slide fits can not only play the role of motion guide, but also bearing capacity is big in linear guide 16, and frictional force is small, and precision is kept Property it is high.
It is set on the bottom plate there are two support 21, connecting plate 22 is fixed on two supports, and the backing plate 12 is fixed on company On fishplate bar 22.During installation, first support and bottom plate are assembled, assembles positioning datum to determine, determines installation site, then pacify again Linear guide etc. is filled, assembly difficulty is reduced.
The upper surface of the push plate is equipped with the first T-slot 141 along its length, and the gripping block is by being placed in this T-nut in first T-slot is simultaneously bolted.T-nut below the gripping block position in the first T-slot of push plate It is adjustable, when needing to adjust, bolt is unclamped, moves gripping block, again fixing bolt.
The upper side of the platen is equipped at intervals with several the second T-slots 101, and the bottom plate passes through screw 102 It is fixed in the second T-slot of the platen with T-nut 103, and passes through positioning key 104 and second T-slot Positioning.Entire flexible fixture is installed on bottom plate, is dismounted on lathe convenient for complete machine.Machine is fixed on by screw and T-nut On bed workbench, positioned by the second T-slot of positioning key and platen.
Negative angle is processed into the inner end and workpiece contact portion position of the gripping block 15, has pushing while top tight workpiece Trend, it is ensured that workpiece precision is fitted in plane on backing plate after clamping, guarantees machining accuracy.Realize headroom above workpiece,
Two locating pieces 13 towards the inner plane of workpiece be respectively formed with the X of CNC machine to Y-direction both direction Opposite zero reference, opposite zero reference of the upper plane of the backing plate 12 as CNC machine Z-direction.Convenient for lathe to knife and volume Journey operation.
It can be seen that should be mounted as a whole on bottom plate, exist convenient for complete machine based on the flexible fixture that CNC is processed when in use Dismounting on lathe;By two groups of push plate driving mechanisms that linear guide and cylinder form be respectively formed X to Y-direction both direction Precise linear guide pair take exercises guiding and support, bearing capacity is big, and frictional force is small, and precision keeps good;In cylinder stroke model In enclosing, various sizes of clamping workpiece can be met without adjustment, more than cylinder stroke range, replaceable various sizes of folder Tight block realizes flexible automation.Negative angle is processed into the inner end and workpiece contact portion position of gripping block, has while top tight workpiece The trend of pushing, it is ensured that workpiece precision is fitted in plane on backing plate after clamping, guarantees machining accuracy.Realize headroom above workpiece; To sum up, the flexible fixture that should process based on CNC fast and reliable automated exchanged cutter square plate part on small size vertical machining center, is had and is dropped The advantages that low operation labor intensity shortens non-cutting time, raises labour productivity, guarantees product quality.
